I just found out from the other reviews, this is a collab item with Pentel! A collaboration with a makeup company and stencil company is amazing ♪ I drew on my hand with a sample and it stayed there for the whole day. I washed my hands after that but... In that way, it's less likely to come off. My eyeliner usually doesn't come off that easily and I don't think this is a bad product.
Liquid eyeliner with a handy and easy to draw design, with a ultra-thin brush developed with the brand, Pentel for a revolutionary application. Enhance your eyes with gloss and deep pigmentation. Film type durable to sweat, water and sebum. Will not fade over time but easily removable with warm water. ※From February 1st, 2017, "Super Sharp Liner A BK-1" is "Super Sharp Liner EX BK-1".
